I just downloaded the in5 Demo to see if it would work for a digital catalog I'm designing. In my test export, everything worked fine except on the pages with scrollable frames. The frames all ended up upside-down except for the photos in them, even scrolling backwards. I used the Ajar Universal Scrollable Frames for InDesign to create the frames if that helps. Did I export it incorrectly? Any advice helps, thanks! LoRes image below of the issue.
This may be related to the "pull tabs" detection.
1) Make sure the top of the content is not above the top of the frame in InDesign.
2) If #1 doesn't fix it, you attach the following as a .js file in the Resources section of the in5 export dialog:
enablePullTabs = false;
